TOOL-MOTOR.

SPECIFICATION forming part of Letters Patent No. 765,100, dated July 12,1904. Application tiled October 12, 1903. Serial No. 176.717. (Nomodel.)

To all whom it 71u17/ cm1/cern:

Be itknown that I, WILLIAM H. Rons, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inTool-Motors, of which the following 1s a specification, reference beinghad therein to the accompanying drawings.

This invention relates to a tool-motor, and particularly to a portabledevice adapted to operate a rotatable tool-holder by compressed air,steam. or other suitable motive agent.

The invention has for an object to provide a casing containing a motorand rotatable toolholder geared to said motor to be driven therebythrough the medium of the motive agent introduced into the casingthrough suitable conducting-pipes.

A further object of the invention is to provide an im proved form ofgearing to properly convey the power from the motor or engine to thetool-holder and adapted to eect the proper reduction of speed andincrease of power in the movement of the parts.

A further object of the invention is to provide an improved form ofoscillating motor adapted to coperate with inlet and exhaust chambers inthe casing and mounted with ports adapted to coperate with said chambersin` the oscillation of the cylinder of the motor.

Other and further objects and advantages of the invention will behereinafter set forth, and the novel features thereof defined by theappended claims.

-In the drawings, Figure l is a central longitudinal section through theinvention. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is asection on the line 3 3 of Fig. l. Fig. A is a section on the line A 4of Fig. 1, showing the cylinders by dotted lines.. Fig. 5 is a centralcross-section at a right angle to Fig. l, and Fig. 6 is a side elevationof the casing.

Like1 letters of reference refer to like parts in the several figures ofthe drawings.

The letter A designates the casing, which may be of any desiredconstruction, but is preferably formed, as herein shown, with an outerchamber A at one side thereof divided by a transverse partition A2 toform an inner chamber A3 at the opposite side of the partition. (SeeFig. 4.) These chambers are separated from the remainder of the casingby a partition-plate A2, through which ports or apertures A5 extend fromthe outer chamber and A0 from the inner chamber. The air, steam, orother motive agent used is introduced through either of the connectionsA7 or AS, while the exhaust escapes from the opposite connection. Properpipe connections may be made at these points by any desired meansH forinstance, as herein shown, a feed-pipe B may be used having a handhold Bpivoted thereon-this pipe being connected by a threaded socket AJintermediate of the connections A7 and AS and provided with aninlet-port B2 and exhaust-port B2, adapted to be turned upon thefeed-pipe B as a pivot and thus register with either of the connectionsA7 or AS. The feed-pipe is provided with a discharge-port Bi lat itsinner end, while the handhold B/ is provided at its outer end with asocket containing a spring B5, bearing against a shoulder -B on theinlet-pipe and adapted to hold the ports B2 and B3 in contact with thecasing. At the opposite sides of the casing from the inletpipe asuitable handle B7 may be provided and secured by threading it into alug BS.

The partition A2, Fig. 4, is provided with a series of bearings B,disposed at proper points and extending through the partition A2 tosupport the cylinders C', disposed between the partition AA1 and thepartition E. These cylinders are provided intermediate of their endswith a journal or pivot-pin C2, disposed at one end in the bearing C andat its opposite end in a similar bearing C3, carried by the partition E,thus mounting the cylinders of the motors for oscillation. The oppositeends of each of these cylinders are provided with a bearing-face C,adapted to travel in contact with the face of the partition A* andprovided with a port C to alternately register with the ports A5 and A6upon opposite sides of the partition A2 in the oscillation of thecylinder, so that the lpiston (l6 within the cylinder will be thusalternately driven by direct pressure in opposite directions. Thesepistons are provided with any ordinary construction of piston-rods C',operative-ly con- TOO `nected to the crank-arm C8, secured upon theshaft or bearing-point D, said arm being provided with a counterbalance-weight C, as usual in this art. The shafts or bearing-points D aresuitably mounted at one end in bearingboxes D, carried in the partitionA", and at their opposite ends in similar boxes D2, carried by thepartition E, one end of said shafts being provided beyond the partitionwith a driving-pinion D3.

Any preferred form of tool-holder may be used in connection with thisinvention; but as illustrating adesirable construction thereof a tubularholder E' is herein shown adapted to fit within the sleeve or collar E2,forming part of the casing and which is supported and braced by thepartition E, surrounding the same, and which partition separates themotors from the driving-gear for the tool-hold er. This holder isprovided at its outer end with any character of tool-for instance,cuttingdies E, as shown, which may be supported within thecarrying-frame E4. This frame is also provided with an annular portionE, extending within the casing and there provided with a drivinggear orrack-teeth F, while the portion is retained in position by means of anannular plate E, suitably secured to the face of the casing. At theopposite ends of the sleeve or collar E2 bearinc` seats or faces' E7 areprovided, upon which bearing-balls E8 are located and adapted at one endto contact with a cone E, carried by the tubular toolholder, and at theopposite end withan adjustable cone E10, threaded upon the free end ofthe holder and adapted to be secured in its adjusted position by alock-nut Eu, thus providing' a ball-bearing for the rotation of theholder to prevent friction thereof.

For the purpose of communicating power from the motor to the tool-holderany desired construction of gearing may be provided, and a preferableform thereof is herein illustrated, which comprises a pinion F', mountedupon `a rotatable sleeve F2, which is fitted to the exterior of thecasing' sleeve or collar E2 and moves freely thereon. The pinion F iskeyed to the lower portion of this rotatable sleeve, while the upperportion thereof is provided with gear-teeth F2, adapted to mesh with agear Ff, which is mounted in the annular frame FG to rotate therein.Secured to the gear Fi, or to the shaft thereof, is a pinion F5, meshingwith the rack-teeth F, carried by the tool-holder. By reference to Fig.3 it will be seen that the series of gears D", F", and F are providedone for each of the motors and suitably disposed at an angle to eachother.

In the operation of the invention the air, steam, or other motive agententering one of the chambers A or A" passes through the ports thereininto each of the motor-cylinders, thereby actuating the piston thereof,which in the movement of the crank-shaft oscillates the cylinder uponits pivot, so as to bring the inlet-port at the previously-charged end0pposite the exhaust-chamber and the former exhaust-port intocommunication with the pressure-chamber. The structure whereby a singleport at each end of the cylinder coperates with the ports for each ofthe chambers permits this automatic reversal of the inlet and exhaust tothe cylinders without the use of any further valve mechanism, as thethrow of the crank-shaft oscillates the cylinder sufficiently for thispurpose. The power derived from the shaft of each of the cylinders istransmitted through the gear carried thereby to the gear and pinioncarried upon the rotatable collar or sleeve mounted on the fixed portionof the casing, and from this the power is again transmitted to theseries of gears meshing with the rotatable collar and through thepinions carried thereby to the annular rack or gear secured to the innerface of the tool-holder, which is thus rotatable in either direction.Vhen it is desired to change the direction of movement, it is onlynecessary to reverse the inlet and exhaust ports of the handheld, whichcan be accomplished by rotating the same upon its pivotal support.

It will thus be seen that the devices necessary for producing atool-motor adapted to rotate any character of tool may all be containedwithin a casing of comparatively small size and adapted for operation byany desired motive agent, while the power being applied from a series ofpoints at an angle to each other secures a smooth and even rotation ofthe holder, which cannot be secured in the application of the power at asingle point.

It will be obvious that the character of the motor, the gear usedtherewith, and the toolholder driven thereby may be altered, as well asother changes made in the details of construction and configurationwithout departing from the spirit of the invention as defined by theappended claims.
